Can't get high resolution with screen server

No matter what I tried I can’t get 1920x1080 on my TV. It looks like transcoding output is about 300x180 and the quality is terrible. My pc is very powerful and my wifi has enough bandwidth to deal with HD video, what should I do?

Can you send a screenshot of the transcoding settings page? Also, did you try turning transcoding off altogether?
What device are you using on TV? What edition and version of TVersity?
